Exactly. It would be great to be able to use an Optimus Prime or something as a mobile development machine. My dream for android development is definitely to be able to build and deploy on a single device.

Of course there's a way to go for that. The range of devices that support mobile docks is very small; I would prefer support for tablets with attached keyboards/mice. If they managed to get this working on tablets, I would definitely consider something like the transformer prime to replace my netbook.
